It was a tough game for Utd Frank...really? It really wasn't, Ajax were a joke. I'm surprised people were calling Sanchez classy because he had multiple 'John Stones' moments where he decided to dribble the ball deep in his box when he had a clear and easy way out for no reason. He did it again later in the game against Fellaini when he could have just played it off the pitch or kicked it half way down the pitch, instead he turned a couple of times and gave it to Fellaini with Fellaini goal side of Sanchez, meaning had he gotten to goal Sanchez would have had to tackle from behind. He also somehow made a half dozen absolutely ridiculously awful passes as in he passed and even if he was off target by 5 yards with simple on the floor passes they had no chance to get to an Ajax player. He did some okay defending but made so so many mistakes.
The rest of the team, dire really, Hargreaves banging on about the perfect tactics Mourinho chose to fight Ajax with when they played the same back 6 without the ball tactic they do against anyone vaguely threatening or in 'big' games or when they have a lead. He was saying they played Valencia with Mata back specifically for the threat of Younes when Mourinho at every club plays that winger slot in to double up as a full back tactic. More importantly Younes was utterly awful throughout. He couldn't deliver a cross all game, he kept coming in and then trying to dink a ball over the top for someone and every time he massively underhit it so it didn't get above chest height and hit a Utd player every time. People accuse Arsenal at times of wanting to walk it in, but there were so many times Ajax, with Traore and Younes in particular, could have taken a shot and decided they wanted to be closer and in a better position. But because they did that they almost never really shot. Quite a few times Traore did beat 1-2 players and then he could shoot but he again decided he wanted to be even closer. Kane is the most obvious player to compare him to, a huge number of his goals come because he's both willing to shoot from anywhere and he's willing to shoot early before anyone expects it. Traore had at least a dozen moments he could have shot and put Utd into trouble, caused a save and a loose ball or at least put the keeper under pressure.
Hererra managed to, in a game with absolutely zero threat from the opposition, still dive a few times including a truly embarrassing attempt to sell that he'd been headbutted. Incredibly boring game, a 'meh' shot being horribly deflected that early led to Utd slipping into that back 6 boring as hell football and Ajax wouldn't have scored if the game had been 90 hours long. Thoroughly disappointed in Ajax's quality and even more so that Utd played such boring defensive football against a side who had absolutely nothing going for them.
